Pattern database
CS2 pattern database — blue gems, Fire & Ice, fades, webs.
Every Counter-Strike 2 skin rolls one of 1,001 paint seeds at unbox. For a handful of pattern-sensitive finishes the specific seed swings the price by an order of magnitude — a stock AK-47 Case Hardened sells for hundreds, the legendary Scar pattern (seed 661) has crossed six figures. This page indexes every weapon for which the community has documented elite seeds.

How the tiers work
- Tier 1 — blue gem / 1st Max / triple-web
- Top of the family. For Case Hardened that’s ≥90% blue coverage on the dominant face. For Marble Fade Fire & Ice that’s the legendary 1st Max ranking. For Crimson Web that’s the highest multi-web count on the playside.
- Tier 2
- Strong but a step below the chase pattern. Case Hardened 80-90% blue; FFI 2nd or 3rd Max; double-web Crimson Web. Still commands a meaningful premium over a generic seed.
- Tier 3
- Notable enough to be worth flagging on the market. Case Hardened 70-80% blue, lower-Max FFI patterns. Worth more than base float would imply, but the premium is modest.
Got an item — what’s its seed?
The paint_seed is hidden inside the in-game inspect link. Paste a link into our Inspect Tool and it’ll decode the def_index, paint_index, paint_seed, and float — entirely client-side, no Steam auth. Cross-reference the resulting seed against the weapon’s pattern page below.
For Case Hardened skins the inspect tool will also surface a tier callout inline when the seed matches a famous one.
Sourcing & methodology
Case Hardened blue-percentage data is pulled from chescos/csgo-blue-gem-calculator (MIT). chescos pre-computes the blue/purple/gold pixel distribution for every seed on every CH weapon by rendering the in-game pattern. We bundle their `result.json` snapshot and classify by dominant-face blue% (Tier 1 ≥90, Tier 2 ≥80, Tier 3 ≥70). Lower-blue seeds are omitted.
Famous-pattern seeds for Marble Fade Fire & Ice, Fade 100%, and Crimson Web are hand-curated from the long-running pattern guides on csgoskins.gg, pricempire.com, profilerr.net, bitskins.com, steamanalyst.com, and the canonical Steam community guides — included only when the seed is documented identically across at least two independent sources.
Card thumbnails show the base skin (not the specific seed) — for actual screenshots of the pattern you’re evaluating, follow the “View live listings” link on each card to CSFloat’s search filtered by exact paint_seed.
